1 Rafael Fonseca MD Chair, Department of Medicine Mayo Clinic in AZ Multiple Myeloma: Is FISH passé? Scottsdale, Arizona Rochester, Minnesota Jacksonville, Florida Mayo Clinic College of Medicine Mayo Clinic Comprehensive Cancer Center

2 Disclosures Consulting: AMGEN, Genzyme, BMS, Otsuka, Celgene, Medtronic, Lilly, Millennium, Binding Site, Onyx, Bayer Speakers Bureaus: None Research: Cylene, Proteolix Patent for FISH based prognostication in MM - about $1500 per year Registered independent Believe in stem cell transplant Dislike wasting your time with this slide

4 Why do risk stratification Old days Early use of bortezomib Overall prognosis New era Pt counseling (“chronic disease”) Post transplant consolidation Tandem SCT? Options for low risk cases

5 Example case 47 y.o. with new diagnosis IgA lambda MM Seen for 2 nd opinion for SCT Treated with RVD Achieved VGPR after 4 cycles Outside report FISH – negative (3 rd pull, path, flow and …) No selection No cIg Sample is obtained and has t(4;14) & -17p13

12 So what is best to identify HR MM? Is there a perfect or best way All systems work Not one system will be 100% (so far) More powerful ones are usually smaller in number None of genetic systems combine clinical variables which may be just as important It is important to understand them!

21 FISH (MGUS n=184, SMM n=116, relapsed MM n=62 and PCL n=26) aCGH (newly diagnosed MM n=224, relapsed MM n=158 and HMCLs n=48) p 53 mutational status was evaluated in relapsed MM (n=84) and HMCLs (n=48) *Tiedemann et al. Leukemia. 2008; 22, Studied 8 patients with 17p deletions at RR 7 did not have deletion at diagnosis Fonseca. Manuscript in preparation

22 Conclusion FISHGEPRNAseqNGSaCGH Clinical useYes No Yes Easy DNA changesYes (large) No (predicts) NoYes MutationsNo Yes No IgH TrxYesYes (spike)Yes No PowerMediumHigh??Medium Can be done with few cells YesYes +/- YesNo Clinicians find of use YesSometimes??? Clonal heterogeneity YesNoYes +/- Low level plasmacytosis YesMaybe

23 Conclusion FISH (cons) Imperfect (GEP more powerful) Technically specialized FISH (pros) Very, very practical Global Sufficient
